Here's a link to a photo of the lollipop switch out of my fan. I believe the thick wire loop on the top and the bottom and their connecting piece that runs vertical along the side of the tower -- you want to keep these intact. The thinner nichrome will connect to it. Under various screws are thin pieces of insulating paper -- like mica -- on the bottom of the switch. You'll probably want to keep that, too. It's fragile to handle so be careful with it.
